If your build does not show the same values, then I *bet*, your test
application is not using the same path as if you're using the coreutils
stat tool. Apparently they access the file via different mount points,
one of them "acl", the other "noacl".

Ssh's readconf.c is using fstat(). If these results are more accurate
with "noacl" defined then why always say "-rw-r--r--" when more
information is available?
